Steps to Reproduce

  1. Run flutter create bug.
  2. Update the files as follows:

main.dart

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  static const bottomNavigationBarTheme = BottomNavigationBarThemeData(
    backgroundColor: Colors.white,
    selectedIconTheme: IconThemeData(
      color: Colors.green,
      size: 24,
    ),
    selectedLabelStyle: TextStyle(
      color: Colors.green,
      fontSize: 12,
    ),
    unselectedIconTheme: IconThemeData(
      color: Colors.lightGreen,
      size: 24,
    ),
    unselectedLabelStyle: TextStyle(
      color: Colors.lightGreen,
      fontSize: 12,
    ),

    // Uncommenting this changes the color of the title but not the icon
//    selectedItemColor: Colors.deepPurple,
//    unselectedItemColor: Colors.deepPurpleAccent,
  );

  @override
  Widget build(BuildContext context) => MaterialApp(
        title: 'Bug',
        theme: ThemeData(
          primarySwatch: Colors.blue,
          bottomNavigationBarTheme: bottomNavigationBarTheme,
        ),
        home: SomeWidget(),
      );
}

class SomeWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) => Scaffold(
        bottomNavigationBar: BottomNavigationBar(
          items: List.generate(
            2,
            (index) => BottomNavigationBarItem(
              title: Text('Item $index'),
              icon: Icon(Icons.ac_unit),
            ),
          ),
        ),
      );
}
  1. Bug is already visible

Expected results:
BottomNavigationBarItem title's color should be green and light green for selected and unselected states respectively.

Actual results:
BottomNavigationBarItem title's color is using the default colors.

The BottomNavigationBarItem title's color is not overriden neither by the selectedLabelStyle nor unselectedLabelStyle attributes (everything should look green).
I managed to change the title's color using the selectedItemColor and unselectedItemColor attributes, but I find weird that the selectedIconTheme and unselectedIconTheme can override the icon's color but the selectedLabelStyle and unselectedLabelStyle can't override the title's color.
